checkmarkWhat is ANES?
The American National Election Studies (ANES) produces high quality data on voting, public opinion, and political participation to serve the research needs of social scientists, teachers, students, policy makers and journalists who want to better understand the theoretical and empirical foundations of national election outcomes. Central to this mission is the active involvement of the ANES research community in all phases of the project. Read More...

checkmarkRelease of the ANES 2008 Time Series Study
The May 2009 release of the ANES 2008 Time Series Study dataset and documentation is now available for download. This release of the 2008 Time Series study differs from the Advance Release of March 2009 in several ways. Additional checks have been conducted on the responses to survey questions. Errata that were reported to us have been reviewed and corrected. Administrative and non-survey variables have been included.

In the coming months, we will continue to provide additional information and enhancements to the data and documentation. Such enhancements include, but are not limited to the continued review of the data, inclusion of additional administrative and derived variables, additional information on the weighting of the data, additional information on the use of the Affect Misattribution Procedure (AMP), and enhanced coding of the open-ended responses. Members of our mailing list will receive notification as this information becomes available. To join our mailing list, please click here.


checkmarkAdvance Release of the ANES waves of the 2008-2009 Panel Study
An Advance Release of the 2008-2009 Panel Study dataset and documentation is now available for download. This release includes the data from the six ANES waves completed in 2008 as well as data from the recruitment and profile surveys.

The Advance Release allows interested users to analyze 2008 political data as soon as possible after the election. The data and documentation will be revised during 2009 prior to the full release of the study.

Standard ANES data quality control procedures have not been completed with the Advance Release data, so users should expect to find errors and inconsistencies in this preliminary file.

In December 2009, ANES will post the full release of the Panel Study data and documentation. The full release will provide complete documentation and public-use data for all 21 study waves, including not only the 7 waves with content and design exclusively controlled by ANES, but also the 14 waves primarily controlled by the fielding organization.

I have a factual question about the 2008 election. ANES is not a source of population data on registration, eligibility, turnout, or vote, nor a source of factual data about political institutions. We are primarily a data collection organization for our own surveys, and all information in our data represents self-report by respondents who are part of scientifically-selected samples.

Report on problems with ANES questions measuring political knowledge and other open-ended questions This report by the ANES Principal Investigators describes what was discovered, offers advice to researchers, and describes how ANES is using the results of the investigation.

A new policy regarding access to ANES 2008-2009 Panel Study Data In the interest of data quality, with particular regard to the unique design of the 2008-2009 Panel, a proposal to change access policy was developed for this study only.

I want an opinion about the 2008 election. ANES is primarily a data collection organization and does NOT, as an organization, offer expert opinion on elections, politics, or any other topics.
